allow only parallel rays from strem of rays
The collimator present in a spectrometer convert the rays from the source to parallel rays .Telescope is used to watch the parallel rays which means for the telescope the object is located at infinity.so that we use telescope.
They have no particular purpose
The purpose of a bicycle is to help people get around.
The purpose of annexure is to acquisition and incorporate an entity.
The purpose is to hold DNA and control your body traits.
The cost of a laser collimator depends on the type of telescope you have. One could be looking at spending anywhere between $70 and $200 on a laser collimator.
A collimator is used to "bore sight" a scope. It will help ensure that the scope is close to being properly aligned.

collimator. The collimator is a device used in radiology to shape and limit the size of the X-ray beam, allowing radiographers to target specific areas of the body for imaging while minimizing unnecessary radiation exposure to surrounding tissues.

A collimator in a spectrometer is used to ensure that light enters the spectrometer in a parallel beam, which helps in improving the accuracy and precision of the spectral measurements. It helps to reduce divergent light and focus the light onto the entrance slit of the spectrometer, resulting in more accurate spectral data.
Parallel beams of light can be created by using a collimator, such as a lens or a mirror, to straighten and align the light rays in a parallel manner. This involves focusing the light from a source into a beam and then passing it through a collimating device. The collimator helps to eliminate any divergence of the light rays, resulting in parallel beams.
A collimator in a spectrometer is used to produce parallel rays of light or particles from a divergent source, ensuring that the incoming beam is well-defined and uniform in direction. This improves the resolution and accuracy of the spectroscopic measurements by minimizing the effects of scattering and allowing for more precise wavelength discrimination. By ensuring that the light entering the spectrometer is collimated, it enhances the overall performance of the optical system.
